The Greater Water Elemental is from the Reaper Bones range and is a transparent blue casting. I've simply dry brushed it with turquoise and white, then gloss varnished it.
The Air Elementals are made from Merino wool felting glued onto a wire armature. They will be mixed in with my previous Air Elementals which were made from the smoke from the Flames of War smoke and fire set.
The air elementals now make a horde.
